Real-Time Transport

RTP is a standard protocol for transporting

Cisco Unified IP Phones use the RTP protocol to

Real-Time Control

RTCP works in conjunction with RTP to

RTCP is disabled by default, but you can enable it

provide QoS data (such as jitter, latency,

on a per phone basis by using Cisco Unified CM.

 

 

and round trip delay) on RTP streams.

 

 

 

 

 

Session Initiation Protocol

SIP is the Internet Engineering Task Force

Like other VoIP protocols, SIP is designed to

end-to-end call.

 

 

 

You can configure the Cisco Unified IP Phone to use

 

 

 

either SIP or Skinny Client Control Protocol

 

 

 

(SCCP). Cisco Unified IP Phones do not support the

 

 

 

SIP protocol when the phones are operating in IPv6

 

 

 

address mode.
